COMPOST SA – “Return it to the Earth” Landfill & Alternative Waste Technologies Landfill is where material is buried & wasted in the ground. Organics are the most problematic material to manage in a landfill: - Severe greenhouse gasses (CH 4 ) are emitted - Significant Odour - Vermin - Leachate (contamination of groundwater) - Subsidence (instability) Along with Landfill, Alternative Waste Technologies (AWTs) are very cost prohibitive and would severely raise the cost of Local Government Waste Management. Along with Landfill, many AWT do not sustainably utilise the resource.
